以上安装成功，并加入开机启动，因为一台服务器后续要用到，所以先安装一下redis

安装完成后，默认无密码，只允许本机访问：127.0.0.1 端口6379

如果你需要使用密码

vi /usr/local/redis/etc/redis.conf

#到500行左右，将requirepass注释去掉，后面修改为你想要的密码
    487 ################################## SECURITY ###################################
    488 
    489 # Require clients to issue AUTH <PASSWORD> before processing any other
    490 # commands.  This might be useful in environments in which you do not trust
    491 # others with access to the host running redis-server.
    492 #
    493 # This should stay commented out for backward compatibility and because most
    494 # people do not need auth (e.g. they run their own servers).
    495 #
    496 # Warning: since Redis is pretty fast an outside user can try up to
    497 # 150k passwords per second against a good box. This means that you should
    498 # use a very strong password otherwise it will be very easy to break.
    499 #
    500 # requirepass foobared

启动脚本就无法stop了，提示(error) NOAUTH Authentication required，因为redis自启动命令没有密码连接设置

     vi /etc/init.d/redis
    #搜索shudown
     42         if [ ! -f "$PIDFILE" ]; then
     43             echo "$PIDFILE does not exist, process is not running"
     44         else
     45             PID=$(cat $PIDFILE)
     46             echo "Stopping  Redis server..."
     47             $REDIS_CLI -p $REDISPORT -a password shutdown
     48             if [ "$?"="0" ]; then
     49                 echo " done"
     50             else
     51                 echo " failed"
     52             fi
     53         fi

#设置密码后必须有密码才能在cli下进行操作
#编辑  /etc/init.d/redis 查找shutdown在前面加上 -a 密码 ，-a前面和密码后面都有空格

如果需要外网访问：

除了要修改 /usr/local/redis/etc/redis.conf 里将bind 127.0.0.1 改成 bind 0.0.0.0 重启redis 
还需要将防火墙里redis的端口 6379的禁止访问规则去掉，参考iptables教程：https://www.vpser.net/security/linux-iptables.html
允许外网访问一定要做好相关安全措施！！！！！！！！！！
